qmp3info(1)

NAME
qmp3info - show info from mp3 files

SYNOPSIS
qmp3info [option]... file...

DESCRIPTION

qmp3info reads a list of mp3 files and prints on standard output some of its parameters: version, layer, sample rate, bit rate, duration and tag.

OPTIONS

-h, --help
    show a brief help and exit.

-s, --summary-only
    show only the summary instead of info from every file.

-v, --verbose
    show also the number of bytes and frames.

-V, --version
    show version and exit.

BUGS

qmp3info reads only the first frame in the stream and calculates the duration supposing that (1) the entire stream is composed by valid frames and (2) all the frames have the same bit rate. this is fast, but not accurate. in case of variable bit rate (vbr) streams, the given results may be far from reality.

tests have been done only with mpeg version 1 layer iii streams, though it may (or not) work with other versions or layers.
